anybody know why a rovan 32cc long block would not start with hy30cc add on parts, they bolt up fine have spark and everything but havnt got a kick any suggestions?
 
Is it getting fuel? Have you messed with the coil? Have you messed with the carb? My guess is that it is a carb setting. Try resetting the carb back to factory. Have you changed the plug? Start by replacing the obvious parts first, ie plugs, fuel, carb if you have one etc. Check the gap on the coil with a business card etc. All of those can prevent an engine from firing. Hope this helps.
 
thanks for getting back to me, its a brand new walbro 998, using stock needle settings checked and double checked flywheel gap tried a brand new plug and also the plug that came from the previous working engine and still nothing :( i am led to believe that the R320 long block is not compatible with the hy30 external parts... i mean i have spark and fuel its so frustrating because i don't know what is at fault
 
i do have some compression 80 psi give or take its a little low i belive but it still should start with low compression, yeah ive ''tried start ya bastard'' and still nothing... it seems like the timing is out but the flywheel is fixed onto the key and cannot be adjusted, i also checked the flywheel key are in the same position on both motors
 
no fail safe of the sort has ever been installed i checked the kill switch it not stuck on either, thanks for your reply's strange friendly people
 
There's no reason why the parts wouldn't be compatible.

If start ya bastard didn't work it must be spark

It would fire at some time even if only momentarily regardless of timing if it's got that much ether in there
 
yeah thats what i thought phill, their is definitely spark going on in there. now i cant even get a refund because he could not confirm it would work before i bought the long block so thats the most frustrating 150 bucks ive ever lost at the moment
 
would the coil on my hy be producing enough spark for this new long block? i don't know... if i do decide to take it somewhere they would charge me more than the price of the longblock. i may have to one day
 
yeah i thought so, i will have another go at it once i get back from the high country
