Hi everyone, I recently found a utility base without a motor and thought it would be a good opportunity to make use of a motor from a worn low arch Mayfair base. When I went to fit it on I found it sat too low and needed spacers of some sort between the engine and base. I compared the side pull full crank on my steel deck rear catcher Victa and noticed an extra bit of space at the bottom of the crankcase measuring about 18mm. Based on this, I fitted nuts and washers to make up an extra 18mm of height for the 125 I wished to fit but found the blade disc seemed to sit too high under the base, so I measured the built in 1cm raises on the Mayfair base (pictured below) and, based on that, reduced the spacing to 1cm, and found the blades about dead level with the skirt on the left and rear but below the front skirt. Is that how it should be or was I right the first time with the blades almost 1cm above the left and rear skirt and the disc just clearing the underside by a hair's breadth? The final pic shows the disc I'll be using. Is it unsuitable? I don't have another utility to use for reference unfortunately. I hope someone can clear me up...
Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
