I'm looking for some ryme or reason at to why I am having to use such high
nitro fuel to get the RPM's up on my la's. Most of the guys in combat use
5-10% and I am using 30%. I drilled the baffle out in the muffler to 27/32 and
am now getting 17,300-17,600. With 5% I get only 16,500 or so. 1,000 RPMs
makes a lot of difference in Combat. What's the deal here? I have 3 LA's and
all 3 run just alike. I'm just having to use higher nitro fuel than I should.
Any ideas??? Thanks Eddie Fulmer AMA 63713 RCCA 694
