Colder plugs usually give a little more power because they allow a sharper tune. Besides the filament, how much heat the plug body retains has an effect too.

If someone is having tuning issue with a bit of a wonky idle that kinda started out of know where would you guys check the bearings or the fuel tank/line first
Engine has never been opened after sealing, all exhaust seals are new. Engine ran like a clock untill we made one of our jumps close to 40 feet of distance and i cased it a few times. The block has no visible cracks and no fuel/dirt build up indicating a leak. Slight bit of weeping on the front bearing, not enough to notice untill you pull the flywheel.

The clutch itself or a bad clutch bearing?

Anyone know a reasonable temp range for a Paloma .21 . From what I was told she went rich basically as she finished up breaking in at the track. Temps went down a lot from about 269 to about 210 it seemed like so looking to start doing a bit more race tune but not sure what are normal temps to look for.

Also, any suggestions on a decent temp gun I am all ears.

Try and spray brekaeclean on the front bearing. You may have an airleak or worn out bearing. just a short burst.

Hi guys,
Just curious if the 41001 manifold from ND is the same as Amain as they look completely different?

Also, I was curious if the Paloma 21 ltd is still a good deal at 159$ or do the prices usually decrease after the racing season is over?

Thanks,

I am curious if they still have more as I heard prior to purchase there were only a few left and they weren't getting any more.

The Paloma is a decent engine for the price but the Rolling is a much nicer engine for the extra $50 if you want a 7port. Any of the 5ports are also a good choice. I am using the Rolling in a buggy right now and really enjoying it. I have an Adam Drake edition 5port that has also been a great engine in buggy and now I have it in my truck. I have also ran the keep-off 4port. It was a great little engine in buggy. Just keep in mind that the extra $30-$50 more for some of the newer engines are well worth it.
