rebuild a imola 186 timing set at 19 btdc ive got compression that would break a horses leg great spark and a soaking plug..bought the carb set up from pheonix scooters due to lack of experience with carbs......any ideas folks?

Is she not trying to fire at all? Start from scratch and dry plug, double check gap. Double check timing. You did put the piston in the right way up, I presume? Strip carb and thoroughly clean and blow through all jets with air duster canister. Check choke plunger is opening fully AND closing off correctly. Check inlet and exhaust are tight and there are no air leaks, including at the head and base gaskets. Come back and let us know how you get on.

first , what are the jets and was it jetted to suit the imola , secondly you say about compression , have you checked the squish with a piece of soilder down the sparkplug hole ?also have you strobed the ignition and i presume you went 19 degrees the right way ?

sorted geezers...no throttle, on with choke and up she fires......1st time build and a move from standard! thanx for advice!

Happy days.

Always good to hear a happy ending.
