That different angle can cause problems with chassis bars in a PM.
If I remember correctly the headers are not interchangeable. Angle of the head around the exhaust ports is different.
If so then I think an abrupt change of 8 degrees will blow the tires off.
So you are not using a timing computer but going to use the switching from mag to trigger? 8 degrees off on rotor phasing when on the trigger is a...
Not if you time it first with the switch in mag position then switch it to crank trigger and time it. This makes the rotor phasing right on. If...
I would close the gap up to .015 and try it. Will not detonate but may feel the missing when going down track. If you are not burning all the...
An Enderle 80a pump only flows 6.81 gpm at 8000 rpm. An Enderle 110 flows 13.1 gpm at 8000 rpm. I don’t think a 80a pump is going to work for you....
Thanks Bobbi
Nitro really has a slow burn rate so the more you add the more timing you have to add. The question is how much. Also a main jet change of only 4...
I agree in what you are saying about using the fuel shutoff but it is obvious his BV is out of adjustment so I would adjust it correctly first...
Just to let you know that your main jet size doesn’t come to play when at idle and oil contamination is caused by rich barrel valve adjustment....
I believe Jeff Burnett has joined up with Noonan Racing and has a Facebook page under Composite Specialities, Inc
You are correct in that you can’t do it with the squirt bottle start
Fuel and timing will show on the plugs. Pre-ignition caused by RFI interference randomly firing the sparkplugs will do it in a flash. Have seen...
The pump going away would have been seen in the plugs
While I agree that the Grid cannot suddenly advance the ignition you can get RFI picked up on the cranktrigger cable that will add pulses that...
Do you have a fuel flow meter on it? Do you tape your fuel shutoff open? What do all the plugs look like?
If you describe your motor and ignition system then somebody here can tell you a good timing start. Normal high safe EGT for methanol is 1050* F....
With an alcohol motor you only want to use the coldest heat range of plug such as a -10 or -11 and you are not going to change. One does not read...
