hi guys, so the engine has been out for a while now. has anyone run into any problems with the longetivity , breakages, tuning issues ?
i have run 2 state titles, and 3 round days with the engine. each titles i ran 5 10 min heats, 20 min semi, and 30 min mains. so in total, like close to 4.5 hours of racing. i replaced the conrod after 1.5 hours. close to 8 lts of fuel minus run in . today was the quickest the engine has gone . i was tuning more for performance today than previously. i have done some more sleeve work and head button mod. id have to say the engine is quite fast. has plenty down low and just wants to keep revving. very happy indeed. also i tried a little something. i turned down an insulator from an OS TZ carb. there is approx half of the insulator left and is a very nice tight fit in the block. i set the tune on the bench and was very close to race tune. i set it on the morning and was very easy to get it tuned. never touched it for the rest of the day, was awesome.
