This is one of those type question youre apt to get varied opinions on, so I will JUMP RIGHT IN AND kick it off with an engineers perspective.
1) To get all the benefits that improved elec switch has to offer n get the most "bang for the buck" I recommend (versus the old stock coil) a matching high energy high voltage coil such as their flame thrower series BE SURE N LET PERTRONIX MATCH THE COIL FOR THE SWITCH as some coils may draw more current n require a higher current rated switch.
2) If you run the elec switch and a high energy high voltage coil, Id widen the stock plug gap to more like at least 0.035 to 0.045 or even a bit more. With the higher energy ignition and wider plug gap you end up with a wider hotter fatter spark which discharges more energy (volts x amps x time) across the plug gap then a stock ignition...THATS JUST PHYSICS
3) Since youre running at a higher firing voltage if you widen the plug gap, you need good quality plug wires and a good clean dirt n oil n moisture n crack free distributor cap. Go with what Pertronix recommends which may be 7 or 7.5 mm etc wires but too big of a wire (8mm) might not fit just right in a stock cap CHECK WITH PERTRONIX
DISCLAIMERS:::::
From an engineers standpoint I wouldnt expect much more if any net HP gain BUTTTTTTTT I would expect better starting and idle performance versus the stock ignition
DO NOT wire it at the wrong polarity you will let the smoke out grrrrrrrrrrrr
Use a good heavy duty battery and 00 gauge battery n starter n ground cables (regardless of any ignition on a 6 volt system) cuz if shes hard to crank n the battery voltage drops drastically the elec ignition may not perform correct
DRAWBACKS a) IF the old points burn you can file them n probably get back to the shop butttttttttt if the elec switch stops YOURE SCREWED b) The elec switch costs more
ADVANTAGES Better starts n idle,,,,,,no points or condensor problems,,,,,more spark gap energy (volts x amps x time) across a wider plug gap is available for that wider hotter fatter spark AGAIN those are the laws of physics IM NOT SAYING THATS NECESSARILY BETTER its just a fact
Your tractor youre choice, best wishes BE SURE N LET PERTRONIX MATCH THE COIL N SWITCH FOR YOUR GROUND AND CURRENT RATINGS ETC

Today's Featured Article - The Cletrac General GG and the BF Avery A - A Bit of History - by Mike Ballash. This article is a summary of what I have gathered up from various sources on the Gletrac General GG and the B. F. Avery model A tractors. I am quite sure that most of it is accurate. The General GG was made by the Cleveland Tractor Company (Cletrac) of Cleveland, Ohio. Originally the company was called the Cleveland Motor Plow Company which began in 1912, then the Cleveland Tractor Company (1917) and finally Cletrac.
