The valve came right tight to the rocker , even after I backed the screw out all the way , it was 100% on TDC on compression stroke, and the push rods should be even when on TDC, the push road behind the exhaust valve was higher than the one behind the intake valve
-
Found the issue !!!!!
out of time ,
when I put the engine to top dead centre , the exhaust valve was a little open and the push road weren’t even , they should be even from my understanding
-
And is the T, F and two lines what your referring to as the index lines ? Hard instructions to wrap my head around lol
-
Battery was at full charge and throttle was wide open ,
when I have the plug out , and roll the engine by the pull start, I look in the hole and get it to the T, there is also an F there and two other lines that are close together.
when I put it to the T the piston is all the way to the top, but my exhaust valve doesn’t seem like it always wants to move.
I set my intake valve to .006, I followed what shadtree sent about finding the compression stroke , and to my understanding I was at compression stroke.
maybe the engine is not in time ? But I’m almost certain I was checking that right
-
I agree ! But so far I haven’t been able to get bike running , lots of great tips and advice , but the thing has air, fuel, spark , I’ve changed everything. Set the valves and the motors in time . I don’t understand why it won’t start.
-
Just wanted to say thanks for all the helps guys , it’s going to a shop, compression is to low , has to be something more internal.
thanks again

Any suggestions for cleaning valves without removing the cylinder head ?
and there’s nothing in the exhaust system :(, I wish it was that easy lol
-

I think I was on compression stroke, I just put cover back on , both valves set to .006, putting back together and gunna try to start it up, exhaust valve was tight , couldn’t fit anything in there
-
Yes I held throttle wide open and has new spark plug , ask just checked timing , it’s showing the T mark in the centre of the hole and the piston is at top, so it’s in time , gunna check the valves now

I’m soon gunna smash the bottle of rum over my head and let the woman beat me with the chicken and put the cigar out on my forehead

Hahahahahaha , made my day lol.
but I can’t see why it would be compression or timing if it was running fine prior to changing the carb 😞

Soooooo guys , I have tried the old carb , a brand new carb from amazon, and the carb off my other foreman which I know works . Still won’t start !!! Poured gas down the spark plug hole , tried another brand new spark plug , still a no go. Pulled gas line off carb and plenty of fuel flow , don’t hear any engine knocks , motor is rolling over fast and spark plug is bone dry . Oil temp sensor underneath the bike the plug is off of it, would this stop it from starting ???
has spark still , good compression, I’m lost lol, it is getting everything it needs, If it was running before the carb replacement , it should run now, but it won’t.
cant see why it would jump time or bend a valve or valves would need adjusting if it was running prior.
any more ideas ?

Yes it is, but I found my way over here lol

And I agree everything does have its breaking point , just seems kind of ironic it happens at that time lol,
I’ll take the top off and peak at the valves , I’m sure they are fine , and the bike shouldn’t have jumped time or anything either

I have done almost all of those thing except put starting fluid in the carb. It has spark , new gas, gas filter, gas is on, kill switch in the middle , air filter is clean, new spark plug , I put it in a battery charger because after rolling it over the battery died , I rolled it over again and it is cranking pretty fast , I’m going to try to boil the carb in lemon juice today just to make sure in case I missed any dirt ,
boil it in lemon juice and water ? Or straight lemon juice?
-
Perfect thank you very much 🙂
-
I did take out the jets on the original carb and cleaned the float bowl ,
maybe I’ll try boiling in lemon juice tomorrow just in case . Thank you very much for all your help and advice , if I can figure out the problem I will keep you updated !

Hmmm if I find out it’s a fuel delivery problem it’s still confusing to me that it was running before a I put the new carb on. And when I put the old carb back on it should’ve fired right back up but it didn’t. I don’t understand how a fuel delivery problem occurred from switching carbs
-
So if I pour enough in the spark plug hole , will the bike actually run and stay running or just temporarily, if I put to much could it harm the engine aswell ?
-
I suppose I could try a little more , that’s always an option
