Man it really shouldn't be that bad if u use a heat gun. At least get the motor to around 170-200 degrees and it should fire up everytime. At least mines did:):)

Well, took the engine out for a pit of club racing/practice this weekend. I was going to do a few pipe comparisons, but when I got to the track, I realize that a few of my SPARE parts boxes were missing. (wife cleaning up around the house) So, I was only able to run the OS 2035 on it. I was very pleased with the results. On the stop watch I got 11:30 from pit to bone dry. Track is on the small side,fairly tight, and probably very suitable for a 2035. The engine ran great, and I was very happy with the overall performance!

Is not the first fire up,it just take a bit long to complete the fully break in.

:nod: I too use the heat gun method. Heat it enough and it fire up the first time.

To break-in a engine. It should fire up first. Without a heat gun. It would be harder and longer. Pain in the a$$. But you will be rewarded later.

I didn't even need to change the conrod and wrist pin. It is the heat gun method which makes it easier to fire up helps safe the rod.
Mine had over 5 gallons now. And I haven't change one part. :lol:

Anyone,

Is it necessary to remove the break in shim after one gallon ?
My first engine was running great with the shim. Fuel Bryon 30%
After I remove it, the engine seems to run hotter. And a little erratic on the tuning.
I put the shim back till now. It all goes back to as it was before.

Question; what does the shim do really ? Will there be a problem if I leave the shim on ?

Adding the break-in shim removes some compression. Removing it will at first be like reducing the shimming on any engine.

I wouldn't remove it strictly based on how much fuel it's had. With the glow plug removed, and engine cold, if you can still feel 'metallic' pinch when turning over the flywheel, leave the break-in shim.

Selling one of these brand new!

:nod:

I am thinking about getting this motor to test it out.

getting this engine very soon. Has anyone tried it with a dynamite 086 nova 9901 or reedy 2039. Thanks for any feedback.

Dynamite 086 and Reedy 2039 are better.both are able to match it.

Thanks james. Cu in mnl 2 ah. But im much much slower than u ah.

I started to run my GTR in my MP9 this weekend, after running it 2L in breakin bench. stil running it rich, but this engine impresses me. Can't wait to go to the track again to race tune it ;)
