The 3 dots always face the exhaust. Some may find this crucial while others find it not important. I always used to mark my underheads so I would always sit them in the same direction.

so in the end the tuned version is always better(meaning faster) than the "stock" version, but cant say that the stock version is not fast, its Very fast also.
Thank you for this answer, I am thinking to pick up 2 of the 353 08's as the pricing is super compaired to last year and I am running at a small to medium track so I am sure the none tuned version will be more then enough for what I am needing.

What brand air filters u guys use on ur 353? I have the older plus 12-3CT and im using a unbranded non retail packaging air filter i bought from murnan many years ago and im finally out of it. It came in pairs with one bottle of oil. I want to change it because im having a problem with the foam unsticking after a couple uses. Any suggestions?

Due to the horrible experiences 8th scale racers made last year with these 3 chamber pipes, EFRA postponed the introduction of these pipes indefinitely.

In other words, stay away from it.
The 2652 is a two chamber pipe, have a look at the Nova Site. The 3 chamber pipe is the 3501.

I ended up going with the 353 09 so I am very interested in the pipe question also. I am currently using the 2630 with great results but I am interested what is noted as best for the 09. I will be trying the 2620 also along with the 2601 as these are the 2 I am thinking to get otherwise I will just get another 2630.

Default Dual adjustment carb

Need help...

Flash .21 - What is the factory setting for the brass adjustment on the very opposite side of the low-needle... would it be flush with carb...or a certain amount of turns open from fully closed?

Also, what benefits do you get by adjusting it and how do you adjust it properly?

Novarrosi's FAQ mentions nothing about Double Adjustment Carb's only Single.

It positions the spraybar into the airflow, see it as a finetuning if you want (and can get) everything out of it.

Default Flash .21 Tuned

Any special advise on what need to do before, during & after break-in this 'fast & furious' engine?
..for info,..I have 35plus21..just after finished break-in (after 10 tanks), eng. compression was completely lost due to inside bearing seized..but once replaced by new bearing, eng. runs perfectly ok till now....just to add on here, I had never experienced lost of compression (after broken-in) on my other .12 engines.
