Make sure it's not air-plane fuel.

Default os tr r spec fuel efficiency!

hey guys

just wanted to comment on the os tr r specs fuel efficiency

i cant believe after running a 5 min heat that i still have half a tank of fuel in my car

the engine still comes back pretty cool at about 80degrees celsius thats truly amazing. my mates collari 12 is lucky to finish the 5 min heat with a drop of fuel left.

However i did notice some fuel/dirt stuck under the low end needle so ive taken apart the carb and sealed it up with carb sealant to try stop that leak.

Default Bearing freeplay

I have a question on the front bearing.
The one on my engine has about 0.5mm of axial freeplay on it. I noticed it when I stripped the engine to clean it. Only done 1 gallon through it. Now I'm a bit puzzled. Why does the bearing get damaged so quickly. As far as I know, there should be negligible axial load on the bearings.

Is it still ok to run the engine with that freeplay? Or will it tear up the con rod and crankshaft?

Any advice is much appreciated.

Cheers...

Con rod koyak after 1 gallon???
How come...?

I think changing conrod is easier than changing bearing. It's a pain to remove and fit. Have to figue out how to heat up the crank case without damaging the other inner bearing...
