Haven't tested it yet, but I think it'll be good. Also as I was tightening I pushed on the other side of the pinch bolt and felt it grab the screw and squeeze the carb a lot better.
That's it. You've gotta do the pinch bolt up tighter than you'd probably like. Glad you sorted it.

No I stick to steel front bearings and ceramic mains. Can't justify the additional cost of front ceramics. Never found a noticeable performance or significant longevity advantage with the front ceramics vs steels.

For the Huge track I'd go for the MM Flash PT or PT/A. Need lots of low and mid power and the PT is great in this regard.

Both of these engines have way more power throughout the band than a flash. I have both murnan modified versions and a stock of each model and they are all awesome at huge. For the WC it'll be virtus hands down (it'll eat the flash for breakfast!).

Also, what about the glowplug? Button head shims? Someone told me novarossi plugs are not so durable,so which ones are? And since its hot in Bangkok, hot as in sweaty manboobs hot, how many shims should I put in the button head?same question for which glowplug number since its hot there. My flash was slow in bangkok, and that was at 150celcius temp!

Anyone else notice the carb they show on the Ison GT is not the one most GT guys would want to use. The idle stop screw would be under the carb if you flip the carb around. I think they are using the onroad carb. It will still work but not preferred.

Lol yes we have noticed but it works You should be looking at a Novarossi CLIO P5 not an ISON. Remember GT is buggy based and the Buggy motors rip! Then you can use the 5 port in your buggy too. Dude you need to look in my pit box Lol! Those 3 motors are all good in GT but they are also killer in buggy and truggy.

I would strongly reccomend the CLIO P5 for GT and Buggy. A little more bottom end and the internals are better.

ISON GT has more power vs CLIO P5. However, CLIO P5 has slight upper hand in quality.....Both engines are great engines for the GT cars.....again it comes down to setup......Oh, and driving of course!

If by power you mean top end?

A little debate ensued Sunday that I need cleared up. Are the Nova Pre-run engines truly broke in and ready for optimum race tuning out of the box?

Not totally broken in as I understand it. Almost there but need finishing off. I'd go about 4 tanks slightly rich and then start tuning it in. You'll know when the motor drops as it will stop going rich and start holding tune.

I was told to do a full fuel bottle(500cc) at a rich setting, don't let it shift, then after that start tunning for speed.
