I started to race tune (but still on the rich side at about the 10th tank)

hey guys i am sure this has been covered on this thread but i didnt take time to read all 700 of them. a guy i race with just bolted this engine in his 8ight t 2.0 and i must say what a turd of an engine !!! what gives, it wont even start running good till it hits about 300 degrees and that cant be good. called associated and they told us to pull the carb and see if the epoxy in the crank is red or black, and if it was black to sent it back and they would replace it. we checked and it was the red. what few threads i read apparently there is an air leak problem between the block and carb so we will try to seal that up any other suggestions ????? also it has an 053 pipe on it.

I just took my crank out after reading this and wanting to put new TKO's in I have one w/ black putty and its hanging on by a thread im sure the next time i was to run it the putty would have came apart do you have and shipping address to send it in to ?

Why get mad? It may be a inconvience but they will fix it for you. At least they didn't deny it like other companies do. I have first hand experience with it.

well i am not mad about it at all, but all the hype about how good this engine ran compaired to what it cost it was supposed to be a great engine, but we just can get any real performance out of it with out the tems being off the charts

What plug is he using? The p4 is the ideal plug for the motor and temps are lower (230-250).

The Reedy has alot of low end snap. Most of the time people will leave the stock gearing in there car and keep leaning the top trying to get top end. I know because I did it. I went up one tooth on the bell and still had really good bottom and the top end was much better. Mine was running 250 last weekend with plenty of power.

well that probably makes more sense than anything else i have heard becuase we left the stock 13 tooth bell on it and it is the top end that stinks, maybe we will throw a 14 on there with a softer clutch spring and see what happens then

For some reason double post much later.

Heys guys I'm about to pick one of these bad boys up and I was just curious if you all had any tuning advise. Such as how it reacts to needle changes and such. I already know I can expect temps in the 260 which is fine with me. I'm really looking forward to bolting it in. Only if it would be here now!!

At our track we are getting 260 - 280 degrees. I'm at 1 1/2 gallons. I love the powerband. A lot of bottom and top end for me. I run a 8 T 2.0. I have read all the posts and others have been seeing the same temps. I love this motor so much I bought two more.

I have a Reedy .21 Buggy/Truggy motor for sale. Used slightly with only 1 gallon through it. The motor is in the original box with the instruction, extra carb venturi, and shims. I have motor sealed it and it's ready to go. There is no damage to the head, since it has been under a truggy body (looks Brand new). If you have any questions please ask.

I'm asking $175 picked up or we can meet at 1/8 Wonder, or ARC. If it needs to be shipped add $10

Thanks

Eric

I can tell you right now, you are rich on top, and lean on the bottom. Richen the bottom 5 hours, and lean the top 2 hours. It will likely need a total of 3 hours leaner on top, but start with 2. You should be able to get great power out of the motor running at 240. Normally, i shoot for 220 as a temp after my 3 minute warm up. That way, during a race, it will be around 250.

Also, once your motor is a gallon old, you need to change the shim. Take the stock shim out, and put the new shim that came in the box in. It raises the compression slightly, and gives you more power.

I cant get my new 121 to idle with out the ignitor. Ive tried new plugs, same result. Any ideas?
The motor is at stock settings.
Running byrons 30% and p4 plugs.

Im not a newb, but its been a while. Like 4 years.

Plus the Carb. Check the crank to see what color the filler is. if it is red you are ok. if it is black, you will need to send it in. When the filler comes out, it does exactly what you are talking about.
